The screw jack operates by rotating the worm of the screw jack, which causes the screw to move up and down, achieving a pushing, pulling, or lifting effect.

Self-locking performance of common thread lead screw electric push rods and screw jacks is ordinary, due to low comprehensive transmission efficiency, most have dynamic self-locking function, enhancing the safety of equipment operation; ball screw electric push rods and screw jacks do not self-lock.

2. The integrated positioning accuracy of the precision location reaches 0.1mm; the position accuracy of the servo electric cylinder can be up to 6um.

3. The control configuration encoder is controlled via a variable frequency drive or controller to achieve closed-loop positioning; for applications with less stringent precision requirements, a potentiometer can be equipped for real-time control.

The synchronous single-speed motor drives multiple rods simultaneously through mechanical connection, achieving synchronized lifting and lowering.

The drive system includes a 12/24V DC motor, single-phase AC motor, three-phase AC motor, and operates without the need for air or hydraulic sources.

Overload protection can be equipped with a safety clutch to prevent overloading; also available is an overload pressure sensor to guard against overloading.

7. High load push/pull capacity up to 250 tons. If you have any questions during the selection process of the elevator, please feel free to call for inquiries.
